BROOM-HEAD.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed September 9, 1914. Serial No. 860,876.

To all whom it may concern Be it known that I, OSCAR T. Coox, acitizen of the United States, residing at Mare tinsville, in the county of Clark and State of Illinois, have invented certain new and useful Improvements in Broom-Heads, of which the following is a specification.

This invention relates to brushing and scrubbing and more specifically to broomheads.

The object of my invention is to provide simple and effective means for binding together the broom straws of which a broom is made, with a view of doing away with the expensive and tedious work of wrapping and sewing the straws together as is customary as brooms are now made. The use of my novel binder in the manufacture of broom-heads will greatly expedite the work, as it is merely necessary to compress together two plates of which the binder is composed, whereupon they will automatically snap together in locked position, which position will be maintained by the natural expansion of the straw when the pressure is removed. Furthermore, the head is made separate and independent of the handle, which is removably mounted to the head for use. This facilitates and economizes space in the packing of the brooms for shipment.

Other objects of this invention not at this time more particularly enumerated, will be clearly understood from the detailed description and drawings forming a part of this specification.

Furthermore, this invention consists in the novel arrangement and combination of parts more particularly described in the following specification and embodied in the claim appended hereunto and forming a part of this application.

Referring now to the drawings which are merely illustrative of my invention Figure 1 is a front elevation of my broom-head with handle attached, partly in section. Fig. 2 is a cross section of the binder plates in locked position, while Fig. 3 is a detail sectional view of the top of the broom-head showing the means for securing the head to the handle of the broom.

Referring further to the drawings wherein similar reference characters designate similar parts throughout the respective views, 1 is a plate member formed in the shape of the upper portion of a broom-head and provided along its inner edge with an inwardly and backwardly turned flange 1. 2 is a cooperating plate member in a substantially similar form as plate 1 and provided along its inner edge with an outwardly and backwardly turned flange 2*, said outwardly and backwardly turned flange adapted to engage with said inwardly and backwardly turnedflange as shown in Fig. 2, when the two plates are pressed together. From the upper end of each of said plates 1 and 2 and integral therewith is a semi-cylindrical extension 3, said extension being provided with a roughened inner surface 7. The said extensions 3 are also formed with threads 4 upon the outer facethereof. An engaging member 5 is slidably mounted upon one end of the broom handle 8, said engaging member being provided with screw threads 6, so that when the handle is inserted in the top of the broom-head, said engaging member may be screwed down upon the extensions 3 to hold the head securely to the handle.

From the foregoing description it is obvious that the straw of which a broom is to be made is secured in a bundle of the desired size so disposed as to give the customary shape to the broom. The plates 1 and 2 are then placed, one on each side of the straw, with the flanged edges thereof in opposing position. The metal being somewhat resilient, the compression of the two plates will cause the flanges thereof to engage in locked position. The natural expansion of the straw will maintain the plates in locked position. In this position, the extensions 3 will form a socket, wherein is to be inserted the broom handle 8. The cap member 5 being screwed down tight over the extensions 8, the roughened interior faces thereof will be caused to engage with the broom handle, thereby securely fixing the handle to the broom head.

The utility, adaptability, and advantages of my improved form of broom-head being obviously apparent, it is unnecessary to further enlarge upon the same herein.

Having now described and pointed out the new and useful features of my invention, I do not limit myself to the shape of certain parts where the shape is not essential, nor do I restrict myself to the exact details of construction shown and described, but mean and intend to claim all equivalents and Variations thereof not departing in principle, from my invention and falling within the purview of the appended claim.

What I claim as my invention and desire to secure by Letters Patent is:

In a device of the kind described, in combination, a plate member curved along the sides thereof, an inwardly and backwardly bent flange formed integral with the sides and top edge of said plate, asecond plate member curved along the sides thereof, an outwardly and backwardly bent flange formed integral with the sides and top edge of said plate, said inwardly and backwardly bent flange and outwardly and backwardly bent flange being adapted to engage with each other when said plates are pressed together, semicylindrical extensions formed integral with the tops of said plate members, said extensions being adapted to form a socket when said plate members are engaged, said extensions provided with a roughened face interiorly thereof, said extensions formed with male screw threads upon the outer face thereof, and a screw threaded cap member adapted to seat upon said extensions.

In testimony whereof I afiix my signature in presence of two witnesses.-

OSCAR T. COOK.
